Ride confidence

Know when pressure really changed

Ever think a tire felt low after a hard hit, then stop to check but everything was fine? TubeWitch shows whether that brutal rock strike, thorns, or debris actually caused pressure loss, so you can avoid unnecessary stops and keep riding with confidence. If you really are losing air, TubeWitch will give you audible and popup alerts based on real pressure data, so you can bail before hitting that next big jump or descent.

TubeWitch can even keep watch in the background, so you can leave your map or favorite screen up and still get audible and popup alerts.
